What is URL Encoding?

URL encoding, also known as percent-encoding, is the process of converting characters into a format that can be safely transmitted over the internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. This ensures web browsers and servers correctly interpret URLs.

How to Use the URL Encoder/Decoder

  1. Input URL or Text: Paste the URL or text you want to encode or decode into the input field.
  2. Choose Action: Click "Encode URL" to convert your text into a URL-safe format, or "Decode URL" to convert a percent-encoded string back to its original form.
  3. Get Result: The result will be displayed in the output field. You can easily copy it to your clipboard.

Common Use Cases for URL Encoding

  • 🔗 Query String Parameters: Encoding data to be passed in a URL's query string (e.g., ?search=hello+world becomes ?search=hello%20world).
  • 📝 Special Characters: Handling special characters like spaces, ampersands, and plus signs within a URL.
  • 🌐 Creating Shareable Links: Ensuring that links with dynamic data are valid and can be shared reliably.
  • 🔍 Building Search URLs: Constructing search queries with filters and special characters.
  • 📊 Data in GET Requests: Passing data to a server through a GET request in a safe and reliable manner.

URL Encoding Examples

Original String:

https://example.com/search?q=hello world&cat=123

Encoded URL:

https%3A%2F%2Fexample.com%2Fsearch%3Fq%3Dhello%20world%26cat%3D123
